I have a Border Collie who knows some great tricks. However, I have been wanting to teach her to backwards weave thru my legs for a while now, and can't seem to find any information how to teach it; short of signing up for a freestyle class. She can already weave forawards thru my legs and backs up, but we can't seem to put it together. She is clicker trained as well. Any suggestions would be great. I am stumped on this one.
